Abstract

Formation of well dispersed cellulose – polymer composites is a challenge. This is magnified when preparing composites using nanoscale materials, where the bulk properties are dominated by interfacial properties. In this chapter, synthetic and processing techniques for improving interfacial properties between cellulose nanocrystals and aromatic polymers are reviewed. A novel and relatively new technique of exchanging sodium ions with bulk, organic cations is shown as a promising approach to improving dispersion while maintaining the potential for cellulose percolation network formation. The technique to shown to be useful in both sulfuric acid hydrolyzed cellulose nanocrystals and maleic acid hydrolyzed cellulose nanofibrils. A water responsive fluorescent dye was used to track water migration in cellulose nanocrystal – single glass fiber – epoxy composites. The cellulose was observed predominantly along the glass fiber – epoxy interface. Measurement techniques for examining the interface and associated properties dominated by the interface are discussed.
